socket实现http
大家好，我写了一个程序：
C/C++ code#include "stdafx.h"#include <iostream>#include <string>#include <ace/ACE.h>#include <ace/INET_Addr.h>#include <ace/SOCK_Connector.h>#include <ace/SOCK_Stream.h>#pragma comment(lib, "ace.lib")#pragma comment(lib, "aced.lib")int _tmain(int argc, _TCHAR* argv[]){ ACE::init(); std::string str = "GET / HTTP/1.1 \r\n" "Host: www.163.com \r\n" "User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:8.0) Gecko/20100101 Firefox/8.0 \r\n" "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 \r\n" "Accept-Language: zh-cn,zh;q=0.5 \r\n" "Accept-Encoding: gzip, deflate \r\n" "Accept-Charset: GB2312,utf-8;q=0.7,*;q=0.7 \r\n" "Connection: keep-alive \r\n\r\n"; ACE_INET_Addr svr_addr(80, "www.163.com"); ACE_SOCK_STREAM stream; ACE_SOCK_Connector connector; int ret=connector.connect(stream, svr_addr); if(0 != ret) { std::cout<<"Error in connect"<<std::endl; return -1; } std::cout<<"sending data:"<<std::endl<<str<<std::endl; ret=stream.send(str.c_str(), str.length()); if(-1 == ret) { std::cout<<"Error in send"<<std::endl; return -1; } str.erase(); str.resize(1024); ret=stream.recv((void *)str.c_str(), str.length()); if(-1 == ret) { std::cout<<"Error in recv"<<std::endl; return -1; } std::cout<<"recived data::"<<std::endl<<str<<std::endl; ACE::fini(); return 0;}
但是为什么服务器返回给我的是错误：
HTTP/1.0 400 Bad request
Cache-Control: no-cache
Connection: close
Content-Type: text/html
<html><body><h1>400 Bad request</h1>
Your browser sent an invalid request.
</body></html>
请大家解答一下。谢谢！
[解决办法]应该是语法错了。具体哪句错了，对着http标准查吧。
[解决办法]某些web站点可以

[解决办法]还是通过wireshark抓包来做比较靠谱
[解决办法]要指明访问那个页面吧
------解决方案--------------------
"GET / HTTP/1.1空格\r\n"
把每行\r\n前的空格去了。
另外
Accept-Encoding: gzip, deflate
你告诉服务器接受gzip编码，返回的可能就是gzip编码，cout输出就是乱码
ret=stream.recv((void *)str.c_str(), str.length());
去看下string的c_str是什么，能这么用么？
访问163主页，返回的数据量是很大的。
[解决办法]Request-Line =Method SP Request-URL SP HTTP-Version CRLF
CRLF前直接是HTTP-Version，没有空格（SP）
[解决办法]服务器走的是1.0协议 比客户端低。
请求Connection: keep-alive属性去除，修改请求协议为1.0看看
[解决办法]没那么麻烦吧，就
"GET / HTTP/1.1\r\nHost: www.163.com\r\nUser-Agent: Mozilla/5.0 (Windows NT 5.1; rv:8.0) Gecko/20100101 Firefox/8.0 \r\n...
一个串（空格没，TOP6），建个连接发送过去，经常弄这，现在163那通常在１００多K（不压缩的），如果实在还有问题，加入我新弄的QQ群：182181974再聊
